On its own, Darktrace/Email™ stops attacks before they reach an employee’s inbox and considers both security teams and the employees themselves. But its value extends beyond email security, increased by its ability to integrate with the wider security ecosystem, including both Darktrace products and external tools. 

Darktrace’s understanding of you and your organization can be applied anywhere your company has data. This unifying approach to cyber security feeds AI outputs into each other, from threat prevention to detection and response, in order to harden the entire security posture autonomously and continuously. The AI also enriches other security solutions an organization has in place by both ingesting and sharing data. This degree of integration transforms a security stack so that it is greater than the sum of its parts. 

Integrating Beyond Email to Enhance Detection and Response 

Integrating email security with other areas of the digital estate bolsters defenses, while reducing required resources. With more data, security teams gain a better understanding of the security stack and how attacks move through the system.

Traditional security solutions do this by either manually aggregating inputs from various tools or using a SIEM without native integrations to collate data. In contrast, Darktrace’s integration provides real-time intelligence communications between products to inform security teams. 

For example, context of network activity can provide more holistic email security. There’s a strong correlation between the websites users visit and the people that they email, which means information like web traffic provides insight into email threats, and vice versa. 

If an organization receives an email from a strange new sender, that happens to be have been sent from a domain nobody has ever visited, that added context could influence the aggression levels of actions taken. Integrations with endpoint security extends this type of informed decision-making to remote environments. These examples highlight the patented power of Darktrace/Network™ and Darktrace/Endpoint™ when paired with email coverage.

Email activity is tied to cloud/SaaS application account activity in an even more direct way. In the case of an account takeover, a suspicious Microsoft 365 login becomes even more suspicious if it is followed by highly unusual email activity, like new inbox rules being created. Too many email security solutions focus on the inbox alone, but viewing these areas in a single scope is critical for security teams wanting to understand the full timeline of an incident. 

To this end, Darktrace creates a 360-degree view of each user and their behavior. This comprehensive view goes beyond native security monitoring tools, allowing security teams to identify instances of data exfiltration, human error, misdirected emails, inappropriate link sharing, unusual log activity, and more. 

In one real-life example, the security team saw an attack from both an email and a SaaS perspective to quickly understand the whole picture, thanks to Darktrace/Email and Darktrace/Apps™. 

Darktrace customers are getting significant value from this integrated security stack. “The whole suite of products has given us 100% visibility across our whole ecosystem, which is fantastic. A lot of times we need to use many products to do that, and with the Darktrace products, I have that all in one,” commented a vice president of enterprise security and fraud management at a major credit union. 

Siloed solutions are a massive pain point in the cyber industry. Most companies have several, layered tools in their security stacks. When there is little to no communication between them, the security team must contend with an inflated workload and misses out on value. They must learn how to navigate several different dashboards, translate between languages and terms, and manually correlate data, in addition to monitoring all the solutions daily. This process makes maintaining security more difficult for the team, especially in a threat landscape with increasingly complex and fast-paced attacks. 

By sending and collecting information to and from other tools that the security team already uses, whether they are a part of Darktrace’s product stack or not, Darktrace/Email optimizes workflows so security teams can reallocate resources to larger, more strategic projects.  

Collaborating Across Email Security and Cyber Risk Management Tools

Syncing email protections with cyber risk management tools even further reduces risk and hardens security.

When emails are received from domain names associated with the brand of the client, an attack surface management tool can automatically analyze if those domains should be included as part of the attack surface scope or trigger malicious domain responses. 

In the other direction, when the attack surface management tool identifies malicious assets, like suspicious domains, spoofing sites, and typo squatters, it can inform email security decisions. With integrations between tools, these malicious assets automatically become watched domains with heightened sensitivity for inbound email. 

This integrated risk reduction can occur internally as well. When security teams look at cyber risk from an internal perspective, they may identify attack paths and high value targets within the company’s digital estate. By leveraging this understanding, Darktrace can determine which employees are critical components of potential attack paths. Once determined, the AI can test them by creating phishing simulations using details like real-life communication patterns and calendar data. These tests generate insights that feed back into Darktrace/Email to harden the environment, for example by heightening sensitivity. 

This demonstrates the benefits of combining Darktrace/Email and Darktrace PREVENT™. As part of the Cyber AI Loop, these connections between email security and cyber risk management are made easy for the security team to understand and act on. One customer noted how this integration had improved its security team’s workflow.  

“The more you use of Darktrace, the better it can correlate on your behalf,” said a Chief Information Officer at a construction company. “That’s why we’re all in with Darktrace now. We now have a holistic Darktrace footprint, which benefits us because we have more of the modules working on our behalf and not having to do the correlations separately or in isolation.” 

Supporting Compatibility with External Security Solutions

Darktrace/Email also works together with external tools. In addition to its mature integration with email providers like Microsoft 365 and Google Workspaces, Darktrace/Email has an open architecture that makes it immensely flexible. It is both API-driven and compatible with syslog, so it can integrate with any security tool and feed into any SIEM or SOAR. 

This unlimited capacity for integration allows Darktrace to detect and respond to threats more precisely with access to more data, as well as reduce the security team’s time-to-meaning by putting all relevant information in a single pane of glass. 

Darktrace/Email is also part of the Darktrace Mobile App, so security teams can view notifications, reports, and remediation actions at any time, even on the go. In this way, Darktrace not only fits into the greater security posture, but also with employees’ day-to-day workflow. 

Finally, Darktrace/Email supports data exports. These translate and share the data it collects within the email environment, allowing the security team to communicate key takeaways generated by Darktrace/Email to anyone within the organization. It can export directly to Microsoft Excel, or any other data analytics tool. This is especially useful for security teams as they work with other departments like IT, compliance, finance, and more. 

Integrations Add Value to the Darktrace Partnership

While Darktrace/Email is a powerful tool on its own, a major source of its value comes from its compatibility with the rest of Darktrace, other tools, people, and processes. 

Deploying multiple Darktrace products builds a robust security ecosystem that enhances detection while breaking down silos and improving workflows, therefore enabling the security team to take on higher-level and more strategic work. By integrating with external tools, Darktrace not only increases its own value but also maximizes the return on investment of other security solutions a team already has.

What the Darktrace Annual Threat Report 2026 Means for Security Leaders

Image of the Earth from spaceDefault blog imageDefault blog image

The challenge for today’s CISOs

At the broadest level, the defining characteristic of cybersecurity in 2026 is the sheer pace of change shaping the environments we protect. Organizations are operating in ecosystems that are larger, more interconnected, and more automated than ever before – spanning cloud platforms, distributed identities, AI-driven systems, and continuous digital workflows.  

The velocity of this expansion has outstripped the slower, predictable patterns security teams once relied on. What used to be a stable backdrop is now a living, shifting landscape where technology, risk, and business operations evolve simultaneously. From this vantage point, the central challenge for security leaders isn’t reacting to individual threats, but maintaining strategic control and clarity as the entire environment accelerates around them.

Strategic takeaways from the Annual Threat Report

The Darktrace Annual Threat Report 2026 reinforces a reality every CISO feels: the center of gravity isn’t the perimeter, vulnerability management, or malware, but trust abused via identity. For example, our analysis found that nearly 70% of incidents in the Americas region begin with stolen or misused accounts, reflecting the global shift toward identity‑led intrusions.

Mass adoption of AI agents, cloud-native applications, and machine decision-making means CISOs now oversee systems that act on their own. This creates an entirely new responsibility: ensuring those systems remain safe, predictable, and aligned to business intent, even under adversarial pressure.

Attackers increasingly exploit trust boundaries, not firewalls – leveraging cloud entitlements, SaaS identity transitions, supply-chain connectivity, and automation frameworks. The rise of non-human identities intensifies this: credentials, tokens, and agent permissions now form the backbone of operational risk.

Boards are now evaluating CISOs on business continuity, operational recovery, and whether AI systems and cloud workloads can fail safely without cascading or causing catastrophic impact.

In this environment, detection accuracy, autonomous response, and blast radius minimization matter far more than traditional control coverage or policy checklists.

Every organization will face setbacks; resilience is measured by how quickly security teams can rise, respond, and resume momentum. In 2026, success will belong to those that adapt fastest.

Managing business security in the age of AI

CISO accountability in 2026 has expanded far beyond controls and tooling. Whether we asked for it or not, we now own outcomes tied to business resilience, AI trust, cloud assurance, and continuous availability. The role is less about certainty and more about recovering control in an environment that keeps accelerating.

Every major 2026 initiative – AI agents, third-party risk, cloud, or comms protection – connects to a single board-level question: Are we still in control as complexity and automation scale faster than humans?

Attackers are not just getting more sophisticated; they are becoming more automated. AI changes the economics of attack, lowering cost and increasing speed. That asymmetry is what CISOs are being measured against.

CISOs are no longer evaluated on tool coverage, but on the ability to assure outcomes – trust in AI adoption, resilience across cloud and identity, and being able to respond to unknown and unforeseen threats.

Boards are now explicitly asking whether we can defend against AI-driven threats. No one can predict every new behavior – survival depends on detecting malicious deviations from normal fast and responding autonomously.  

Agents introduce decision-making at machine speed. Governance, CI/CD scanning, posture management, red teaming, and runtime detection are no longer differentiators but the baseline.

Cloud security is no longer architectural, it is operational. Identity, control planes, and SaaS exposure now sit firmly with the CISO.

AI-speed threats already reshaping security in 2026

We’re already seeing clear examples of how quickly the threat landscape has shifted in 2026. Darktrace’s work on React2Shell exposed just how unforgiving the new tempo is: a honeypot stood up with an exposed React was hit in under two minutes. There was no recon phase, no gradual probing – just immediate, automated exploitation the moment the code appeared publicly. Exposure now equals compromise unless defenses can detect, interpret, and act at machine speed. Traditional operational rhythms simply don’t map to this reality.

We’re also facing the first wave of AI-authored malware, where LLMs generate code that mutates on demand. This removes the historic friction from the attacker side: no skill barrier, no time cost, no limit on iteration. Malware families can regenerate themselves, shift structure, and evade static controls without a human operator behind the keyboard. This forces CISOs to treat adversarial automation as a core operational risk and ensure that autonomous systems inside the business remain predictable under pressure.

The CVE-2026-1731 BeyondTrust exploitation wave reinforced the same pattern. The gap between disclosure and active, global exploitation compressed into hours. Automated scanning, automated payload deployment, coordinated exploitation campaigns, all spinning up faster than most organizations can push an emergency patch through change control. The vulnerability-to-exploit window has effectively collapsed, making runtime visibility, anomaly detection, and autonomous containment far more consequential than patching speed alone.

These cases aren’t edge scenarios; they represent the emerging norm. Complexity and automation have outpaced human-scale processes, and attackers are weaponizing that asymmetry.  

The real differentiator for CISOs in 2026 is less about knowing everything and more about knowing immediately when something shifts – and having systems that can respond at the same speed.

CVE-2026-1731: How Darktrace Sees the BeyondTrust Exploitation Wave Unfolding

Default blog imageDefault blog image

Note: Darktrace's Threat Research team is publishing now to help defenders. We will continue updating this blog as our investigations unfold.

Background

On February 6, 2026, the Identity & Access Management solution BeyondTrust announced patches for a vulnerability, CVE-2026-1731, which enables unauthenticated remote code execution using specially crafted requests.  This vulnerability affects BeyondTrust Remote Support (RS) and particular older versions of Privileged Remote Access (PRA) [1].

A Proof of Concept (PoC) exploit for this vulnerability was released publicly on February 10, and open-source intelligence (OSINT) reported exploitation attempts within 24 hours [2].

Previous intrusions against Beyond Trust technology have been cited as being affiliated with nation-state attacks, including a 2024 breach targeting the U.S. Treasury Department. This incident led to subsequent emergency directives from  the Cybersecurity and Infrastructure Security Agency (CISA) and later showed attackers had chained previously unknown vulnerabilities to achieve their goals [3].

Additionally, there appears to be infrastructure overlap with React2Shell mass exploitation previously observed by Darktrace, with command-and-control (C2) domain  avg.domaininfo[.]top seen in potential post-exploitation activity for BeyondTrust, as well as in a React2Shell exploitation case involving possible EtherRAT deployment.

Darktrace Detections

Darktrace’s Threat Research team has identified highly anomalous activity across several customers that may relate to exploitation of BeyondTrust since February 10, 2026. Observed activities include:

Outbound connections and DNS requests for endpoints associated with Out-of-Band Application Security Testing; these services are commonly abused by threat actors for exploit validation.  Associated Darktrace models include:

  • Compromise / Possible Tunnelling to Bin Services

Suspicious executable file downloads. Associated Darktrace models include:

  • Anomalous File / EXE from Rare External Location

Outbound beaconing to rare domains. Associated Darktrace models include:

  • Compromise / Agent Beacon (Medium Period)
  • Compromise / Agent Beacon (Long Period)
  • Compromise / Sustained TCP Beaconing Activity To Rare Endpoint
  • Compromise / Beacon to Young Endpoint
  • Anomalous Server Activity / Rare External from Server
  • Compromise / SSL Beaconing to Rare Destination

Unusual cryptocurrency mining activity. Associated Darktrace models include:

  • Compromise / Monero Mining
  • Compromise / High Priority Crypto Currency Mining

And model alerts for:

  • Compromise / Rare Domain Pointing to Internal IP

IT Defenders: As part of best practices, we highly recommend employing an automated containment solution in your environment. For Darktrace customers, please ensure that Autonomous Response is configured correctly. More guidance regarding this activity and suggested actions can be found in the Darktrace Customer Portal.
